When Will It Get Too Hot to Hold the Summer Olympics?
By 2085, rising temperatures will mean that just 33 cities can safely host the games.
It may be winter in Rio right now, but Olympians are competing in temperatures that run between 70 and 90 degrees Fahrenheit. And environmental health researchers now say the forecast for future games is looking even hotter—perhaps too hot for Olympic athletes to handle.
In a commentary published last week in the journal The Lancet, a team of public-health researchers warns that, if global temperatures continue to climb, only a handful of cities will be cool enough to host the summer Olympics by 2085.
